Froth Flotation and Gold Extraction - Manhattan …
Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).

Gold Flotation - Mineral Processing & Metallurgy
Even when recovery of gold and silver from such ores by flotation is low, it may be advantageous still to float off the minerals that interfere with cyanidation, roasting, and leaching or possibly to smelt the concentrate for extraction of its precious metals. Cyanidation of the flotation tailing follows, this being simpler and cheaper because of prior removal of the cyanicides.
Silver Gold Recovery Flotation Process
A total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation-cyanidation process gives an overall extraction of 95%. The installation is much more compact and its capital cost far less than one embodying fine grinding and cyaniding of the whole tonnage, and it can be run with lower operating, maintenance, and depreciation costs.
Gold extraction - Wikipedia
Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values. Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by
Advancing flotation process technologies to …
The process used to extract gold is largely dependent upon the ore deposit and the mineralogy of the ore. A flotation process is one method used throughout the industry to recover gold. It’s a very cost-effective method for concentrating gold, and is a desirable process used for the upgrading of low-sulphide and refractory ore for further gold recovery treatment. Froth flotation is a process ...
